This invention relates to telecommunications systems, specifically methods for managing user plane payload formats and encoding in communication networks. The problem addressed is ensuring compatibility between the user equipment (UE) and the mobile switching center (MSC) when their preferred payload formats or encoding differ, which can disrupt communication. The method involves an access transfer control function (ATCF) that acts as an intermediary. The ATCF receives signaling from the UE, including parameters describing the payload format and encoding the UE prefers. The ATCF forwards these parameters to the UE's remote peer. The ATCF also receives signaling from the MSC, including parameters describing the format and encoding the MSC has selected. If the MSC's parameters differ from the UE's, the ATCF configures a media gateway to modify incoming user plane packets from the remote peer to match the MSC's requirements before forwarding them. When communication needs to shift from the UE to the MSC, the ATCF signals the UE's original parameters to the MSC to ensure continued compatibility. This approach ensures seamless data transmission by dynamically adapting payload formats and encoding to resolve mismatches between the UE and MSC.
